Some of the victims died in the fire at the Gabriel House Assisted Living Residence, while others died after they were transported to local hospitals.

About a week after a devastating fire at the Gabriel House in Fall River, officials shared on Tuesday what they have learned about the origin of the deadly fire. Massachusetts State Fire Marshal Jon Davine said a preliminary investigation revealed two possible causes: an electrical issue with an oxygen tank or the improper disposal

Following a meeting with Fall River officials, Healey said the state was releasing $1.2 million for more emergency response personnel.

An investigation into the source of the fatal fire at a Massachusetts assisted living facility last week classified the cause as "undetermined," though officials believe it was an accidental ignition

A fire that killed 10 people at a Massachusetts assisted-living facility was unintentionally caused by either someone smoking or an electrical issue with an oxygen machine, investigators said Tuesday.

Smoking or an oxygen machine issue may have sparked the deadly fire at Gabriel House Assisted Living Facility in Fall River, Massachusetts, officials said Tuesday. Also, the owner of the facility faces a new lawsuit.
